T0 all whom it may concern: v

Be it known that I, FnANcis H. VOLLERY, a citizen of Switzerland, residing at Mount Clemens, in the county of of Michigan, have invented certain new and useful Improvements in Therapeutic Vibrators, of which the following is a specification,

had therein to the accompanying drawings.

This invention relates to a device for the treatment of diseases of the nerves and vital organs by contact with a vibrating body, and the invention has particular reference to a manually-operative device designed to be applied to the body of the person to be treated while being manipulated by the operator.

The invention consists in the peculiar and novel construction of a vibrative contact member and in combination therewith of a pendant member slidingly supported. thereon and adapted to set the contact member into vibratory action by manual operation, all as more fully hereinafter described, and shown in the accompanying drawings, in which- Figure I is a perspective view of my theraeutic Vibrator, and Fig. 2 is a detached vertical central section through the pendant member. j

A is the vibratory Contact member, which consists of a single piece of metal wire, preferably of hard Bessemer steel, one end c of which is rigidly secured into a handle B and the projecting portion of which is bent into a closed loop, a portion l) of the loop, forming a continuation of the handle portion, being preferably straight and in alinement with the handle portion.

Upon the curved portion of the loop, which is to be brought into contact with the body of the person to be treated, is sleeved a tubular sheath of rubber C, which prevents the metal of the loop from being brought into direct contact with the body. Upon the straight portion l) of the loop is supported the vibrative pendant member D, which consists of an apertured head d, which is adapted to slide quite freely upon the part l) of the loop, a shank e secured thereto and a counterbalance f slidingly adjustable on the shank, the whole being preferably made of wood or of other suitable material, the handle B beling of like material.

In practice the operator holding the device by the handle with one hand and applying it Macomb and State to the part of the body of the person to be treated actuateswith his freehand the pend ant member back and forth upon b by just touching the shank at a point between the head d and counterbalancef. If the point at which the operator touches the shank in actuating the pendant back and forth is properly chosen, (it being near its center of gravity,) the sliding motion of the pendant will be accompanied by a quivering or tremulous motion, which in turn causes the loop to vibrate strongly. The counterbalance f tends to keep the pendant in the vertical plane of movement without effort on the part of the operator to guide it, and by adjusting it higher or lower it modifies the vibrations within a certain desired limit, thus constituting, in effect, a governor. also preferably place upon the shank a sheath E, which may be simply a short piece of rubber tubing sleeved upon the shank. Its object is to prevent the hand of the operator from producing a deadening elect upon the pendant in the manipulation thereof.

It will be understood that the size of the bore g in the head of the pendant is a factor in producing the desired result. The best effect is obtained by making it just large enough to permit the pendant to swing quite freely like a pendulum upon the part l) of the loop. The loopl may be of any suitable shape, although I make it preferably circular, with the part t forming a chord, and the best effect is obtained by making it continuousthat is, the end h should be brought into metallic contact with the other end and, if desired, may be brazed or welded thereto.

My device is very simple and at the same time very effective and is especially adapted for self-treatment.

Having thus fully described my invention, what I claim isj l. A vibrator comprising a vibratory contact member and a member adapted to have a vibrative movement thereon, the vibratory contact member consisting of a metal bar or wire bent in the form of a loop, one end -of the bar projecting beyond the other end and forming a handle portion for the loop.

2. A vibrator comprising a vibratory contact member and a member adapted to have a vibrative movement thereon, the vibratory contact member consisting of a metal bar or wire bent in the form of a loop, and a handle l in which one end of the bar or wire is secured,

IOO

. from the head and a counterbalance to the head slidingly adjustable on the shank.

4. In a Vibrator, the combination of a eony tact member formed of a single piece of metal bar or Wire partially formed into a loop With a projecting handle portion and an adjacent straight portion in alinement with the handle portion and forming part of the loop and a pendant member slidingly engaging with the straight portion of the loop.

5. In a vibrator, the combination of a contact member formed of a single piece yof metal bar or Wire partially formed into a loop with a projecting handle portion and with an adj jacent straight portion in alinement there-` with and .forming a part'oi the .loop,.a sheath upon the looped portion, a handle upon the handle portion of the loop and a pendant member slidingly engaging With the straight portion of the loop and adapted to be reciprocatingly actuated thereon.

6. In a vibrator, the combination of a contact member comprising a handle and a loop formed of a single piece of Wire and secured to the handle, a part of the loop adjacent to the handle being straight and in 'alin'ernent with said handle, and a pendant :member comprising an apertured yhead slidinglyengaging with the straight portion of the loop, a shank depending therefrom, a counterbalance .adjustably carried by the shank and a sheath upon the shank.

In testimony whereof I aliiX my signature in presence of tWo Witnesses.
